T 0 all whom it may concern:

Be it known that 1, OSCAR H. DESMARAIS, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented a new and useful Attachment for Linotype-Machines,

This invention has reference to improvements in attachments for linotypeor other type setting or casting machines, and its purpose is to causean economy in power in machines of this class. i

When an operator has finished a take, it is customary to extract thecast lines in the galley and to place them on the bank. This takes anappreciable time and during such time the operator often fails to shutoff the time the power is doing no useful Work.

By the present invention it is made impossible to remove the lines inthe galley chines of the character to which this invention relates, and,consequently, the present switch, so that the current must be turned oifby a suitable manipulation of the switch before it is possible to removethe slugs in the galley, and the power will remain off until theoperator returns to resume his work. material saving of power iseffected, whether the operator so desires or not.

The invention comprises an attachment in the nature of a lock mechanismunder the control of an electric switch and so arranged that when theswitch is in the on or active position the galley which receives thelines as they are cast is locked in such a manner that the lines cannotbe removed from the galley, and when the switch is in the. off position,then the lock mechanism is moved out of the path of removal of the linesfrom the galley. i The invention will be best understood i from aconsideration of the following detailed i description taken inconnection with the accompanying drawings forming a part of thisspecification, in which draw1ngs- Figure l is a face view of theattachment i showing its relation to the electric switch. Fig. 2 is aside elevation of the same. Fig. 3 is a view similar to Fig. 1, butshowing the l i l attachment applied to a linotype machine, the partsbeing in the position assumed when the power isshut off.

Similar numerals of reference are employed to indicate correspondingparts throughout the several figures of the drawings.

Referring to the drawings there is shown a bracket or frame 1 carryingan electric switch 2, which may be of the ordinary snap type with itsrotary member under the conti ol of the usual manipulating button 3. The

invention is not confined to the use of this particular type of switchsince any suitable type of switch may be used, but a snap type ofswitchiis in common use in type setting and casting machines, and such aswitch has positive points of stopping, being usuallyrotated clockwiseas viewed in Figs. 1 and 3 and indicated by the arrow in Fig. 3.

In Figs. 1 and 2 the typesetting machine has been omitted but is,inpart', shown in Fig. 3.

Fast on the frame or bracket 1 is a tubular member 4 having one end bentat an angle, as shown at 5, and lying substantially tangential to an arcdrawn from the center of the switch as an axis. lhis angle member 5 ofthe tube 4 is formed with a longitudinal slot 6 for the reception of anannular cam member 7 fast on the stem of the switch, so;

3 is turned. The cam portion 8 extends through approximately one halfthe circumference of the cam member so as to be active when the switchis moved to the on position, and to be inactive when the switch is inthe off position. The cam portion 8 is provided with a shoulder 9 formedby cutting away a portion of the cam surface, and this cam portion isadapted to extend entirely across the angle portion 5 of the tube 4 andthrough another slot 10 formed in the wall of the tube portion 5opposite the slot 6.

Entering the upper end of the tube 4 is a rod 11, and the end of the rodremote from that entering the tube 4 carries a plate 12- adapted to moveinto and out of operative relation to'the galley of which galley isindicated at 19 in Fig. 3. The lower end of the late 12 may be dividedand straddle an ofiset portion 13 of the frame or bracket 1 and move inrecesses '14 on opposite sides of the offset portion.- of the as to berotated therewith when the button-- the linotype machine,

frame Tl, thereby 'co aoting with the rod 11 to cause a smooth and-evenmovement of the plate 12.

lloused within the tube 4 between the lower end of the rod 11 and thecam 7 is a series of metal balls 15, the lower member of the seriesengaging either the shoulder 9 or the peripheral surface of the camportion 8 of the cammember. shoulder Qremote from the point where itmerges intothe peripheral portion of the cam member is a projection ortooth 16. The cam portion 8 terminates at the two .ends in abruptradialshoulders 17.

in the position of the parts, shown in Fig. 1, the plate 12 is in itsactive position, in which position it is in such relation to the galleythat it is impossible to withdraw from the galley the cast lines, and inthis position the switch is on. By rotating the switch v clockwise, asviewed in Fig. '1, a-sufiicient distance, the switch is turned to theoil position shown in .hig. 3. -When this position is reached, the camsection 8 has moved through the angleportion-5 of the tube 4,

until the shoulder 1? remote from the shoul-' der 9 has reachedsubstantially the position opposite that shown in big. 1. Under these 7conditions the cam section 8 is entirely out or the path or the balls 15and these balls gravitate to the lower end of' the angle secp the tongueso that the galley is locked against tion 5 or the tube 4 and the rod 11and plate 12 lollow the balls so that the plate 12 is correspondinglylowered, and is thereby moved out 01 coincidence with the galley, sothat the castlines or type theupper onus of which are shown exposed at20 in rig. 3 may be readily removed from the galley to be ultimatelyplaced on the bank. 'lhe balls 15 are prevented fiom escaping from thelower end of the angle extension 5 by a suitable plug 18'. llnoer theseconditions the power has been cut oil, and, consequently, there is nowaste or power while the operator is away from themachlne. when theoperator returns he inust lurther rotate the switch to again cut in thepower, and in doing so the shoulder 17 adjacent to the shoulder 9 firstengages the lowermost of a series of balls 15 and iorces the same alongthe angle extension 5 ol thetube 4 and up into the tube 41,

'mately the projection or tooth 16 will ride.

elevating the rod 11 and the plate 12. Ultiunder the lowermost ball andthe series of balls will fall slightly until arrested by the shoulder 91It is now impossible to reverse the direction. of the. switch since thetooth or projection 16 and shoulder 9 co-act to clamp the lowermost ballagainst the inner wall of the tube extension 5, this structure therebyroviding a positive locking means which automatically acts when theswitch is onfv of the to prevent a retrograde movement switch.Meanwhile, the electrlcal ortions of the switch, if the switch be of t esnap At the end of the ,means movable to apply and cut oil power, andconnections tor transmitting the I I movement of the powerCOIitIOlll-I-lg means to 125 corpse type, have snapped into place, andthe oircult is completed, while the plate 12 has been elevated to aposition closing the gal-lief} chamber to access by the operator Bymeans of the attachment forming the subject matter of this presentapplication, the operator is forced, whenever he wishes-to, remove the.type lines or slugs from the'machine, to cut off the power, and sinceit is therule to remove these type lines or slugs whenever the machineis to' be left for a period of time, as when the operator leaves theroom or the building, it will be seen that it is impossible for theoperator to leave the ma chine running under any conditions when hewould be away from the machine for any material period of time. Thedevice, therefore, acts to economize power and the expense of runningtype setting and casting machines. I

The operator may, instead of lifting the slugs from the galley, removethe galley itself with the contained slugs. To prevent the removal ofthe galley with the slugs therein, before the power is shut off, a lowerpart of the plate 12: is cut and turned upto form a tongue 12, but atsubstantially right angles to the-plate, so that when the plate israised, this tongue 12 is flush up against the bottom of the galleywhich latter at such oint carries an extension then engaged by removalas well as the slugs. Therefore, it follows that the slugs cannot beremoved from the machine either by being lifted out 100 of the galley orby lifting out thegalley and contained slugs.

In Fig. 3 the attachment is shown applied to a machine known as thelinotype machine,

the galley 19 being shown with the attach- 105 means for locking thegalley for the reception of type lines or slugs, and a power controllingmeans acting to move the galley'loolr to the 115 unlocked position whenthe power is turned off, and to move the same to the locked positionwhen the power is turned on.
